Struct postgres_parser::nodes::Expr

pub struct Expr {}

Expr generic superclass for executableexpression nodes

All node types that are used in executable expression trees should derive from Expr (that is, have Expr as their first field). Since Expr only contains NodeTag, this is a formality, but it is an easy form of documentation. See also the ExprState node types in execnodes.h.
